Abstract

An ion mobility spectrometer includes a spectrometer housing (10) and, within the housing, an ion mobility spectrometer cell (12), a volume of vapour absorbent material (30), and a fan (38) for inducing a flow of recirculating cleaning air through the cell (12) and the absorbent material (30). In the preferred arrangement the vapour absorbent material is held in close proximity with the cell, providing the possibility of constructing a miniature instrument without the need for any external air supply.
